UARTs and PCI buses.UARTS and PCI busesUARTs (Universal Asynchronous Receiver/Transmitters) UARTS are designed to convert sync data from a PC bus to an async format that external I/O devices such as printers or modems use. UARTs insert or remove start bits, stop bits, and parity bits in the data stream as needed by the attached PC or peripheral. They can provide maximum throughput to your high-performance peripherals without slowing down your CPU.
PCI® (Peripheral Component Interconnect) Bus enhances both speed and throughput. PCI Local Bus is a high-performance bus that provides a processor-independent data path between the CPU and high-speed peripherals. PCI is a robust interconnect interface designed specifically to accommodate multiple high-performance peripherals for graphics, full-motion video, SCSI, and LANs. |
